Aperture long-lanceolate, the margins nearly parallel. Colu- 

 mella binodose, the upper nodule dentiform, nearly horizontal, 

 the lower nodule large, obtuse. Truncation of the columella

The columella is very thick, arcuate, and has a quite consid- 

 erable swelling at the upper part, referred to in the description, 

 somewhat inexactly, as " unilamellate. " It is smaller than

 callus, and the small tooth at its upper part, referred to above.
